Specification of Letters Patent.

Patented March 16, 1909i.

Application filed May 26, 1908. Serial No. 435,041.

' To all whom it may concern: Be it known that I, Grnsrxrv A. UGGEL-'DAHL, citizen of the United States, residing at Seattle, in the countyof King and 5 State of Washington, have invented certain new and usefulImprovements in Railway- Switches, of which the following is a speci-.fication. This invention relates to railway switches of that classwhich isv actuated from and 25 a railway truck and the front end of acarand showing sin-application of the invention thereto; Fi

partly in horizontal section of the same; and Fig. 3 is a ersp'ectiveview of the wheel 3 which is emp oyed in manipulating the throwingof theswitch. 1

The reference numeral 5 indicates the rails of the main line of a railwa-track; 6, the-rails of a turn-out or branch inc; and 7 35 a switchtongue which is ivoted at 8 so as to be free to swing, as or inary, todirect a 68.1, when traveling in the direction indi- .;cated by thearrow in Figs. 1 and 2, to continue upon the main-line beyond the-switch0 or be caused to proceed therefrom upon the branch-line.

According to my invention a'bar'9 is connected to the sw1tch-tongue by astud 10 depending from the'latter and arranged to 45 extend transverselytoward the rail at the opposite side of-the track. Connected with saidbar and between the rails, as by a pin 1 1, is the arm 12 of alongitudinally disposed lever 13 which is fulcrumed to a pin 14 so as.

so to vibrate in a horizontal plane and carries upon the extremity ofitsother arm 15 an upwardly extending block 16 which is des rably formedtotaper from its mid-length' toward both'ends, asshown-in- Fig. 2.-

2 is-a view partly in "plan and i suitable and rigid support, such, forexample,

as a strap 17 bolted to a track-tie.

18 isacasing which is located adj acentqf the bar 9 and secured to arigid meniberof the track as, for instance, to the web of a 60.guard-rail .19 and extending axially. through the casing is a bolt 20having a flattened end 21 which protrudes from the casing and urged by aspring 22; positioned within the casing, to seat within either ofnotches 23 and 23, provided in said bolt. These notches are sopositioned and. spaced with regard to the bolt as to lock the bar. ineither of its two positions when'the latteris' shifted in the openingor. closing of the 7o;-"- switch. This locking engagement, as will beevident, is maintained through the power of the spring and to aflordmeans whereby the bolt may be retracted to allow of a longi- .tudinalmovement ofthe bar the notches are -formed with slopingsides.

Extending through the front. platform of a car, represented by 24, in.an upright tubular standard 25 which -'is rigidly secured in place, asby bolting a flange 25 of the standar 89 to such platform and sooketingthe" lower end. thereof in a frame, such as 26.

Extending axiall through thestandard is a shaft 27 provide with asquared'top end 28 and at the bottom with afoot 29.arranged radially ofthe shaft and of an approximately triangular shape in horizontal sectionThis. shaft is adapted for rotation and is movable in an axial directionto an extent governed by the interference ofthe frame 26 as to elevatlonand by a shoulder 30 within the standardbeing engaged by a set-collar 31upon the shaft to limit the downward movement ofthe shaft, the latterbeing, however, such as to permit the ,foot of the shaft engaging onlythe lever-block lG. A bindingscrew 32 passes through a screw-threadedaperture 33 in the standard and serves to retain the. shaft inraised-position and to pre-' vent any. accidental loosening of theengagement between thes'haft and-such screw, one

or more annular grooves, as 34, is advan tageously employed upon theshaft and whereinto thee'nd of the screw may-be in: serted and thusrender the hold positive.

Mounted upon the aforementioned square (.1 end of the shaft is a b and;wheel;35 wiha. hub' 36 of less length than that of Such v squared endand extending dcwnwardiy The fulcrnrn p n 14 may be secured toany 1 and3, he

om the a; hig 37, see Figs.

, standard to receive any shock due tothe im-I Whose office is to.ei'igage in cirouniferen'tially disposed notches, such as 38, providedin the top of the standard 25. These notches, two in number, are tpacedso that when said lug is engaged in either, the shaft will b e. held inrotative. position to corespondingly present the foot 29 in condition toengage the block 16 for swerving the same to change the condi tion ofthe switch. 39 is a washer secured to the top end of the shaft toprevent the Withdrawal of the wheel 35 when the latter is employed inraising the shaft into its inoperative position.

in Fig. 2 the switoh-tongue is-shown to have the main-line of track openand also' representing the positions assumed by the connecting bar andthe lever under such a condition. When the tongue is to be swung toclose this linearid open the branch the shaft is first lowered and thengiven suiiicient rotation to cause the shaft-shoe to be di rooted sothat as it is carried onward by thev car it will engage the lever-block16 and force the same into the position indicated by broken lines inFig. 2, and the lever being correspondingly swung efiec'ts through the'connecting bar 9 the changed. cond1t1on of the-switch. Insuchoperationlthe springpressed bolt 20 is by reason er the inclinedengaging edges of the notches 23,, 23 wedged outward to permit of themovement of the bar and when'the alteration in the switch is coinpletedthe tongue prevented against displacement through the vibrationsininarted from a moving caror other causes.

other than a strong force transmitted laterally as is accomplished bythe lever when .acted upon by the devices carried by a movand means forthrowing the same, means to ring car.

To change the angular direction of the foot requires'only sufiioientelevation of the hand wheel to withdraw the lug 'thereoi from theengaging notch, whereupon the wheel and shaft is turned in unison untilthe lug is in the radial plane of the other notch and where-- into it isseated "and afiiords a lock with the pact of the shaft-foot with thelever block and also to withstand the strains in overcoming the inertiaand the movement of the switch-tongue While I have illustrated theinvention in connection with a switch commonly used in street-railways,I do not wish to understood as confining myse inasmuch as the onlymodification required to adapt it to steam railways is to extend the bar9 entirely across the track so as to be connected to the switch-pointsthat are there utilized instead of a tongue, hereinbe'fore considered.

to such application,

standard having spaced notches in its upper end, a shaft disposed insaid standard and formed with arr-annular groove, a binding screwcarried by the standard and adapted to have its free end project in saidgroove, a shoulder formed in said standard, a collar carried by saidshaft on the interior of said standard to seat on said shoulder, theupper end of said shaft projecting beyond the upper end of the standardand being squared, a hand wheel on said squared part of the shaft, adownwardly extending lug on saidhand wheel to engage in said notches ofthe stand and, a washer on the upper end of said scpiared part of saidshaft and spaced from said-hand wheel to limit the upward movement ofthe latter, and a foot on the lower end of said shaft.

2. In combination with a switch tongue and means for throwing the same,means on the car foractuating said. throwing means composed of a tubularstandard having spaced notches in its upper end, a shaft in said.standard having a foot on its lower end and a squared part on its upperend, a hand wheel arranged to slide on said squared part and adapted torotate said shaft, means on the outer end of said squared part of theshaft to limit the u ward movement of said hand wheel, and a ug carr edby said hand wheel to engage 111 a selected one of said notches of saidstandard. I

.3. In combination with a switch'tongue,

actuate said throwing means composed of a tubular standard on the'car, ashoulder on the interior of said standard, a shaft arranged insaidstandard, means on the shaft to engage the shoulder to restrict thedownward movement of the shaft, said shaft having a groove therein,means carried by the standard to engage in. said-groove "to hold theshaft in elevated position, a foot on the lower end. of said shaft, ahand wheel for rotating said shaft arranged 011 the upper end thereof toslide thereon, means whereby said hand wheel is secured againstmovement, and means to limit the upward movement oi the hand wheel.
